my uncle follows the same chain in Dec, everybody knw the situation during that time, anyway he took 12801 from Gaya jn (train was on time) and reached delhi around 11 am next day and at the same time Pachim exp was also arriving ndls. so for a few min he was in a safe side.
I will suggest you, If travelling single, Go for it as now punctuality of 12801 is restored to normal and it will reach ndls late by MAX 3hr.
